以1995年考题为例。
The purpose of non-REM sleep is even more __43__. The new experiments, such as those described for the first time at a recent meeting of the Society for Sleep Research in Minneapolis, suggest fascinating explanations __45__ of non-REM sleep. (95)
43. A. subtle B. obvious C. mysterious D. doubtful
45. A. in the light B. by virtue C. with the exception D. for the purpose
分析:只要细心寻找即可发现,文章开头说的“the purpose of non-REM sleep”和结尾的“_of non-REM sleep.”遥相呼应。所以45填D。而在后文的fascinating就指示43应填与其同义的词,故43题选C,因为两者都表示“神秘的、为之着迷"的意思
二.从惯用法、搭配角度考虑
注意固定的搭配,包括动词与介词的搭配、动词与名词的搭配以及形容词与名词的搭配等,同时要根据内容选择正确的短语。例如:
Here’s a fellow who just walked into a bank and helped himself_____so much money.
A for B by C to D of
分析:表示“自取,随便拿”这个意义的短语是help oneself to 故答案为C
